The PCBs finally arrive, and it is time to test if anything went wrong, or if we need to make the Rev-B of the board, It almost works as spect it but i decided to make some changes in the board to increase the specs. This the board with all the components on their respective places.

REV-A Front face

REV-B Back Face

The new specs will be that we can light the PBBW in more tones that just the Red, Green and Blue LEDs one at a time as I put a single resistor in the common anode of the RGB LED, in that configuration just one color of each RGB LED can be turn on at the same time, but if we add a resistor for each LED we could make some color combinations, like a nice rainbow contained in our device. I have also change the form factor of the Buzzer, now it will be a SMT.

So let me show you how the new schematic looks like:

SCHEMATICS REVB

And a 3D look of the board before send it to fabrication:

So now we are ready to send the GERBER Files for fabrication, and in a week from now you will see working.
